Example—the galaxy extended
In the previous chapter, we built a basic keyboard navigation to fly around a paper plane, demonstrating the spring camera. What goes for mouse interaction also goes for keyboard interaction—you can make it as smooth as you like. The navigation we created wasn't particularly smooth, although the spring effect helped. But the spring camera is built into Papervision3D and using it has some limitations, unless you were to tweak or extend the code.
In the next couple of paragraphs, we will not only build keyboard navigation that runs more fluently, we will also demonstrate how to implement several camera perspectives as seen in games.
We will build an application based on the example from Chapter 5 in which we created a galaxy of planes, a sphere that represents the earth, and a paper plane that we can fly around. The application will have the following features:
Advanced keyboard navigation for the paper plane
Dynamic zoom
Multiple camera perspectives
Although the example...
